A fully implicit WENO scheme on stratigraphic and unstructured polyhedral grids
(Journal article; Peer reviewed, 2019)Many authors have used higher-order spatial discretizations to reduce numerical diffusion, which can be particularly pronounced when simulating EOR processes involving active chemical substances that are transported by ... -
Accelerating multiscale simulation of complex geomodels by use of dynamically adapted basis functions
(Journal article; Peer reviewed, 2019)A number of different multiscale methods have been developed as a robust alternative to upscaling and as a means for accelerated reservoir simulation of high-resolution geomodels. In their basic setup, multiscale methods ... -
Approximate Implicitization of Triangular Bézier Surfaces

Data Assimilation for Ocean Drift Trajectories Using Massive Ensembles and GPUs
(Chapter, 2020)In this work, we perform fully nonlinear data assimilation of ocean drift trajectories using multiple GPUs. We use an ensemble of up to 10000 members and the sequential importance resampling algorithm to assimilate ... -

Numerical Analysis of NREL 5MW Wind Turbine: A Study Towards a Better Understanding of Wake Characteristic and Torque Generation Mechanism
(Journal article; Peer reviewed, 2016)With the increased feasibility of harvesting offshore wind energy, scale of wind turbines is growing rapidly and there is a trend towards clustering together higher number of turbines in order to harvest maximum yield and ... -
Numerical benchmarking of fluid–structure interaction: An isogeometric finite element approach
(Journal article; Peer reviewed, 2016)In this paper we describe and evaluate an isogeometric finite element program, IFEM-FSI, for doing coupled fluid–structure interaction simulations. We investigate the role played by employing higher polynomial orders and ... -
The Open Porous Media Flow Reservoir Simulator
(Peer reviewed; Journal article, 2020)The Open Porous Media (OPM) initiative is a community effort that encourages open innovation and reproducible research for simulation of porous media processes. OPM coordinates collaborative software development, maintains ... -
Optimal Surface Fitting of Point Clouds Using Local Refinement
(SpringerBriefs in Earth System Sciences;, Book, 2023)This open access book provides insights into the novel Locally Refined B-spline (LR B-spline) surface format, which is suited for representing terrain and seabed data in a compact way. It provides an alternative to the ... -
The application of flow diagnostics for reservoir management
(Journal article; Peer reviewed, 2014)Flow diagnostics, as referred to herein, are computational tools derived from controlled numerical flow experiments that yield quantitative information regarding the flow behavior of a reservoir model in settings much ...
